桥架配线前应消除槽内的污物和积水；缆线布放前应核对型号规格、程式、路由及位置与设计规定相符。

Before wiring the cable tray, the dirt and accumulated water in the groove should be eliminated; Before laying the cable, the model specifications, program, routing, and location should be checked to ensure they match the design specifications.

在同一桥架内包括绝缘在内的导线截面积总和应该不超过内部截面积的40%；缆线的布放应平直、不得产生扭绞，打圈等现象，不应受到外力的挤压和损伤；缆线在布放前两端应贴有标签，以表明起始和终端位置，标签书写应清晰，端正和正确；电源线、信号电缆、对绞电缆、光缆及建筑物内其他弱电系统的缆线应分离布放。

The total cross-sectional area of wires, including insulation, within the same cable tray should not exceed 40% of the internal cross-sectional area; The laying of cables should be straight, without twisting or looping, and should not be subjected to external compression or damage; Before laying the cable, labels should be affixed to both ends to indicate the starting and ending positions. The label writing should be clear, upright, and correct; Power lines, signal cables, twisted pair cables, optical cables, and cables of other weak current systems in buildings should be separated and laid out.

各缆线间的非常小净距应符合设计要求；缆线布放时应有冗余。在交接间，设备间对绞电缆预留长度，一般为3至6米；工作区为0.3至0.6米；光缆在设备端预留长度一般为5至10米；有特殊要求的应按设计要求预留长度；缆线布放。

The minimum clear distance between each cable should meet the design requirements; There should be redundancy when laying cables. In the handover room, the reserved length for twisted pair cables between equipment is generally 3 to 6 meters; The working area is 0.3 to 0.6 meters; The reserved length of optical cable at the equipment end is generally 5 to 10 meters; If there are special requirements, the length should be reserved according to the design requirements; Cable laying.

在牵引过程中，吊挂缆线的支点相隔间距不应大于1.5m；布放缆线的牵引力，应小于缆线允许张力的80%，对光缆瞬间非常大牵引力不应超过光缆允许的张力。

During the traction process, the distance between the supporting points of the hanging cable should not exceed 1.5m; the traction force for laying the cable should be less than 80% of the allowable tension of the cable, and the maximum instantaneous traction force on the optical cable should not exceed the allowable tension of the cable.

在以牵引方式敷设光缆时，主要牵引力应加在光缆的加强芯上；电缆桥架内缆线垂直敷设时，在缆线的上端和每间隔1.5m处，应固定在桥架的支架上，水平敷设时，直接部份间隔距施3~5m处设固定点。

When laying optical cables by traction, the main traction force should be applied to the reinforcing core of the cable; When the cables are vertically laid in the cable tray, they should be fixed on the brackets of the tray at the upper end and every 1.5m interval. When laid horizontally, fixing points should be set at intervals of 3-5m for the direct part.

在缆线的距离首端、尾端、转弯中心点处300~500mm处设置固定点；槽内缆线应顺直，尽量不交叉、缆线不应溢出桥架、在缆线进出桥架部位，转弯处应绑扎固定。

Set fixed points at a distance of 300-500mm from the beginning, end, and turning center of the cable; The cables in the trough should be straight and avoid crossing as much as possible. The cables should not overflow from the bridge, and they should be tied and fixed at the entry and exit of the bridge and at the turning points.

垂直桥架布放缆线应每间隔1.5m处固定在缆线支架上，以防线缆下坠；在水平、垂直桥架和垂直桥架中敷设缆线时，应对缆线进行绑扎。

Vertical cable trays should be fixed on cable supports at intervals of 1.5m to prevent cables from falling; When laying cables in horizontal, vertical, and vertical cable trays, the cables should be tied.

４对对绞电缆以24根为束，25对或以上主干对绞电缆、光缆及其他信用电缆应根据缆线的类型、缆径、缆线芯数为束绑扎。

Four pairs of twisted pair cables should be bundled with 24 pieces, and 25 or more pairs of main twisted pair cables, optical cables, and other credit cables should be bundled according to the type, diameter, and number of cable cores.

绑扎间距不宜大于1.5m，扣间距应均匀、松紧适应；在竖井内采用明配、桥架、金属桥架等方式敷设缆线，并应符合以上有关条款要求。

The binding spacing should not exceed 1.5m, and the buckle spacing should be uniform and the tightness should be suitable; Cables shall be laid in the vertical shaft using methods such as exposed installation, cable trays, metal cable trays, etc., and shall comply with the relevant provisions above.
